IMPROVEMENT IN THRASHINGNIACHINES.

Specification formingpart of Letters Patent No. 150,694, dated B Iay 12, 1874; application filed March 20, 1874.

To all whom it may concern:

Be it known that I, WVM. M. LEYDE, of New port, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in Grain-Separators, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part ot' this specification.

My invention relates to improvements in grain-separators; and consists in the combination and'arrangement of certain devices for the more thorough and rapid separation of the grain from the straw, as hereinafter more fully described.

In the drawings, Figure l represents a plan view; Fig. 2, alongitudinal section, taken at c a', Fig. l; Fig. 3, detached views of the pickers and beaters.

K represents the main body of the machine, and K the front end or portion thereof, where the thrashing-cylinder is placed. A is the grain-carrier, and Gr the straw-carrier. The grain-carrier A extends from near the front and bottom of the machine, just beneath the thrashingcylinder, upward and rearward. The straw-carrier consists of a broad trough, G, which projects some distance over each side of the main body K of the machine, extending upward and rearward from the end of the grain-carrier.

The broadening of the upper portion of the machine along thaty portion that contains the straw-carrier or secondary carrier, is of greatv importance. I am aware that machines have been made wherein the secondary carrier has been given greater breadth than the primary carrier; but as neither have been made to extend beyond or even over the sides of the main body of the machine, it has been accomplished by a considerable narrowing of the primary carrier, and a consequent decrease in the receiving capacity of the separator. By my invention, that portion only oi' the machine is enlarged which incases the secondary carrier, and the mainbody of the machine is not altered in the least. The machinery, the truck,

and the relation of the bed to the truck are.

none of them altered in the least, while the capacity of the machine is very greatly increased, since the primary carrier can occupy the entire breadth of the main body ot' the machine, and the enlargement of the secondary carrier be beyond the sides of the main body of the machine, and can readily be attached as an alteration to the machines that are now in use without altering other parts.

B represents a picker, placed over the graincarrier A at a position on same, so as to as-l sist the straw and grain up the carrier as it is delivered from the thrashing cylinder. This picker consists of a cylinder provided with four projecting iianges, b, which assist the grain and straw up the carrier, at the same time producing a sort of beating action against the straw to shake out loose grain. D is a picker, placed over the lower end of the strawcarrier G, just at the end of the grain-carrier A in a position to receive the straw from the grain-carrier. This picker D consists of a cylinder provided with two projecting anges, d, the outer edges of which iianges are curved, as shown in Fig. 3, so as to present a convex outline. The beater F is a iiat board pivoted at the ends, and having both edges beveled and curved, so as to present a convex outline, as shown. These pickers B D and beater F receive proper rotary motion through the medium of the bands and pulleys g, h, c', Snc., which also actuat'e the grain and straw carriers A Gr.

The object of making the edges of the beater F and the anges d of the picker D curved or convex, as shown, is for the purpose of producing a beating or agitating action against the straw, at the same time forcing it from the center of the trough toward the outside, thusV evenly and thinly distributing it over the carrier, and thereby allowing the grain to escape more readily through it. By this arrangement herein described, using a short grain-carrier and a very broad strawcarrier, and providing them with the pickers and beaters, all arranged and constructed substantially as shown, the grain is thoroughly and rapidly separated from the straw.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with the primary carrierl g A and secondary carrier G, the picker D, provided with the Convex-'edged blades or anges d, substantially as and ioihe purposes shown.

2. In Combination withthe primary carrier A, the secondary carrier Gr, Jche sides of which project over the main body ofthe machine, substantially as and for the purposes shown.

3. The combination of the primary carrier A, picker D, and beater or agitator F, eachv provided with Convex-edged blades with secondary carrier G, made of a Width greater than the primary carrier A, substantially as described.

In testimony that I claim the foregoing` I have hereunto set niy hand this 18th day of March, 1874.

IVM. M. LEYDE.
